ASTM Mirror finish Aluminum Steel Welded Pipe

Characteristics of Aluminum Tube: as a kind of high strength duralumin, heat treatment can be strengthened, in annealing, hardening and hot state plasticity medium, spot welding weldability is good, with gas welding and argon arc welding aluminum tube has the tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve the corrosion resistance.

 Aluminum tube is widely used in all walks of life, such as: automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and so on.Widely used in need of good formability and high corrosion resistance, but strength requirements are not high products, such as chemical equipment, food industry equipment and storage containers, cookware, pressure tank, sheet processing workpiece,
